An integrative architecture for a sensor-supported trust management system.

Trček D - Sensors (Basel) (2012)

Bottom Line: With this methodology and architecture sensors play a crucial role.The architecture presents an already deployable tool for multi and interdisciplinary research in various areas where humans are involved.It provides new ways to obtain an insight into dynamics and evolution of such structures, not only in pervasive computing environments, but also in other important areas like management and decision making support.

ABSTRACT
Trust plays a key role not only in e-worlds and emerging pervasive computing environments, but also already for millennia in human societies. Trust management solutions that have being around now for some fifteen years were primarily developed for the above mentioned cyber environments and they are typically focused on artificial agents, sensors, etc. However, this paper presents extensions of a new methodology together with architecture for trust management support that is focused on humans and human-like agents. With this methodology and architecture sensors play a crucial role. The architecture presents an already deployable tool for multi and interdisciplinary research in various areas where humans are involved. It provides new ways to obtain an insight into dynamics and evolution of such structures, not only in pervasive computing environments, but also in other important areas like management and decision making support.

f2-sensors-12-10774: Sensor-focused trust management model.

Mentions: Taking into account the above factors, a corresponding model is given in Figure 2. In this model T denotes the set of time increments t, Δ denotes the set of observed facts based assessments δ (i.e., agent's physiological responses and deeds), and denotes the set of other agents' opinions. A denotes the set of assessments reported by agents. Thus αi (t + 1) = φi (A(t), Δ(t), Ξi(t)) denotes the i-th agent major trust in step t + 1 that is calculated on the basis of A(t), Δ(t), Ξ(t), Further, the mapping from the set of major assessments to the set of deeds based assessments is defined by function η: δi = ηi(α). And finally, the expressed opinion α is modeled by function ζ, i.e., αi = ζi (α). It can be noted that trust forming factors are modeled by functions φ, η and ζ, as well as feed-back dependencies.
